How to fail a nerve conduction test


We can test three types of nerve: motor, sensory and mixed. Read More. Went to orthopedic dr, and he discovered OK, we have an individual in my company who has claimed that he is getting nerve pain and tingling in his left leg. The doctor started setting up the test for the left leg. Immittance audiometry -- This test measures the function of the ear drum and the flow of sound through the middle ear. Nerve conduction test side effects like what you describe is more common that we'd like to think, especially minor or mild symptoms.


Emg and ">nerve</a> conduction studies are very good at detecting nerves that have been damaged to the point where the nerves are losing function, but are not always sensitive to less severe damage that is causing nerve irritation without loss of function, or to disease elsewhere in the body, such as in the brain or spinal cord. Neurologists use EMGs to test the electrical activity of a skeletal muscle to provide a medical diagnosis on a patient. NCS testing give physicians important information about nerve and muscle function. Speech test. In the nerve conduction studies (NCS), various nerves, usually in the arm or leg, will be stimulated with a small, harmless electrical pulse.


Just because the test show "normal" doesn't always mean it is. Performance Objectives: At the end of the exercise the student should be able to: 1. ) Automated Point-of-Care Nerve Conduction Tests: Automated nerve conduction tests are performed with portable devices that allow NCS to be done in an office without specialized training rather than performed in conjunction with a needle EMG in a laboratory. Nerve conduction study can identify nerve damage. Electromyogram (EMG) and Nerve Conduction Studies: About These Tests What are they? An electromyogram (EMG) measures the electrical activity of your muscles when you are not using them (at rest) and when you tighten them (muscle contraction).


Repetitive nerve stimulation is a variant of the nerve conduction study where electrical stimulation is delivered to a motor nerve repeatedly several times per second. These nerves run outside the central nervous system (brain and spinal cord) and provide stimulation to the face, torso, skin, extremities, blood vessels, and internal organs. Nerve Conduction Study. NCV can determine nerve damage and destruction. Dr.


Many patients come to the test anxious because they have heard how painful it is. If you want to see if the wire is functioning properly, you need to make sure that electricity can run through it. the American Association of neuromuscular and electrodiagnostic medicine developed this video so you know what to expect during a nerve conduction study and electromyography or EMG test you've been sent to the EMG clinic to evaluate your nerves and muscles the tests will help the doctor who referred you determine if your muscles or nerves […] Electromyography/Nerve Conduction Study (EMG/NCS) is a two-part test to diagnose disease of the nerves and muscles. No neuropathy, no carpel tunnel, no nerve damage. If indicated, look at external auditory canals, eardrums.


I had the nerve conduction test today and I was not impressed with the neurologist doing the test. Let me know how that conversation goes, will you? Nerve conduction study also called nerve conduction velocity, measures how fast an electrical impulse moves through your nerve. Patient Education At Birmingham Neurosurgery & Spine Group, P How to fail a nerve conduction test. Hook electrodes to the skin that lies over a particular nerve or muscle, and then discharge a small electric shock. These tests may be an important part of a spine patient’s work-up by their doctor.


Last week was when I finally had a none comp exam done. Start studying Nerve Conduction Velocity. Nerve conduction study's wiki: A nerve conduction study ( NCS ) is a medical diagnostic test commonly used to evaluate the function, especially the ability of electrical conduction, of the motor and sensory nerves of the human body. Also called an electroneurography, EneG, or nerve conduction study, a nerve conduction velocity (NCV) test is a measurement of the speed of conduction of an electrical impulse through a nerve. How did he get a false positive? Any Neurologists use EMG to test nerve conduction speeds in order to assess neuropathic and myopathic disease states.


Median to ulnar comparison recording over digit 4 (which receives dual innervation) can be helpful to confirm CTS (prolonged peak or onset latency of >0. The first part is called a nerve conduction test. Learn vocabulary, terms, and more with flashcards, games, and other study tools. An EMG is usually done in conjunction with a nerve conduction velocity (NCV) test, which measures electrical energy by assessing the nerve’s ability to send a signal. This test is usually ordered by your podiatrist or other physician but completed by a Neurologist or Physiatrist.


An audiologist will test your capacity to understand speech. (In many nerves the signal travels about 120 miles per hour!) Although the suddenness of the stimulation may surprise some, most people are fairly comfortable during nerve conduction studies. The signals are made to travel along the nerve by applying small electric pulses to the nerve at one site and recording the response at a different place along the nerve. It will only show the degree to which you have lost feeling. This is one of the tests that may be performed to confirm the diagnosis of nerve injury.


EMG and NCS are tests that measure the electrical activity of the muscles and nerves of the body. A nerve conduction test shows that the main nerve that the current goes through is intact. Electromyography, the second part of the test, allows the consultant to see if the nerve that goes from the spinal cord to individual muscles is damaged. The nerve conduction test cannot test the who;e nerve. By observing the change in the muscle electrical response (CMAP) after several stimulations, a physician can assess for the presence of a neuromuscular junction disease, and differentiate between presynaptic and postsynaptic Unfortunately, one of the first steps in dx Polymyositis is the nerve conduction test and then a muscle biopsy.


Rinne's test: Air vs. These are diagnostic tests to check on how a patient’s muscles and nerves are functioning. Many physiatrists face big coding problems when billing for nerve conduction studies (NCSs) and electromyography (EMG). We recommend using a pinprick test to map out the nerve deficit. Introduction Review nerve physiology/ anatomy Purpose of testing It is designed to familiarize the reader with the basic aspects of nerve conduction studies and needle examinations and can serve as a guide to the test, a preparation for the EMG rotation, or as a simple means for better understanding of the indications, preparations, interpretation and performance of EMG Nerve and Conduction studies.


Damaged nerves don't transmit messages as quickly as they should. They all failed, after lots of testing. This may be because nerve conduction studies identify nerve damage but not brief nerve symptoms, thus explaining negative results with symptoms of short duration. Before diagnosing peripheral neuropathy, your physician will review your medical history and conduct a physical exam and neurological evaluation. A nerve conduction test assesses nerve damage and measures how fast an electric impulse is transmitted through the nerves.


He then setup the connections for the I failed nerve conduction test in leg How to test cranial nerves All the information, content and live chat provided on the site is intended to be for informational purposes only, and not a substitute for professional or medical advice. A-Delta Pain Fiber Nerve Conduction Study Benefits Patients With Spinal Pain Of 151 pain fiber nerve conduction studies administered to patients with cervical and lumbar spinal pain, 56% changed treatment plans for the patient and 35% confirmed the planned treatment. Electromyogram (EMG) and Nerve Conduction Studies (NCS) are two components of the same test usually performed together to test whether your muscles and nerves are working correctly. Injury to the superficial peroneal nerve where it exits the fascia is purely a sensory injury and results in chronic pain. 6% sensitivity in detecting lumbar nerve-root function pathology as confirmed by epidurograms 2.


I'm curious, did the test show if any nerve conduction loss is coming from up at the front of neck/shoulder/chest? I'm also curious to see what the neurologist says. The chiropractor and MRI scans showed that things were not okay. A neurological evaluation, which consists of a number of simple and painless tests, is usually performed to diagnose peripheral neuropathy. This test takes 15 to 45 minutes to complete, depending on how many areas are being studied. This will be done at different points to see if there is anything that is blocking or impeding the transmission of the impulse.


Nerve supply to the sweat glands is affected immediately following the nerve injury. Effective January 01, 2013, CPT Codes 95900, 95903, 95904 have been deleted! Your New Nerve Conduction Studies CPT Codes for 2013 (CPT Codes 95907-95913) are the following: 95907 Nerve conduction studies; 1-2 studies 95908 Nerve conduction studies; 3-4 studies Nerve Conduction Velocities (NCV) A nerve conduction velocity test, or NCV, measures the rate of nerve conduction (how fast an electrical impulse moves through your nerve). This test can determine nerve impingement/pathology (pain causing) within the spine (nerve root level) where EMG and Velocity Tests fail. I am hoping that they will skip the nerve test and just do the biopsy as I have heard that really the only true way of knowing you have Poly is the biopsy. Other Tests: Your physician order additional tests to confirm and document the diagnosis of CTS if surgery is being considered.


It turns out that this test signal can be generated by a simple electrical stimulus and the conduction wave measured by electrodes on the skin further down the nerve pathway. How To Correctly Code Your EMG Studies To Maximize Your Reimbursement? Needle EMG is the recording and study of electrical activity of muscles using a needle electrode. 5 medical tests that could save your life (and 5 to skip Nerve conduction test side effects like what you describe is more common that we'd like to think, especially minor or mild symptoms. It assesses the health state of the muscles and nerves and also rules out any other condition that may have the same Rinne's test: Air vs. If left untreated, Lumbar Stenosis can lead to loss of sexual ability and loss of bowel and bladder control.


Everybody's relationship with pain and stimulus is different, of course, but it is my belief that the post-emg symptoms you experience are ultimately due to a lack of nutrition in the body. He then setup the connections for the A nerve conduction test, also known as a nerve conduction study (NCS) or velocity (NCV) test, uses electrical impulses to assess nerve damage. How does a nerve conduction test tell the difference between acute and chronic nerve problems. During an NCV test, electrodes are placed on the skin and impulses are sent to them. Bragg responded: Shows function loss.


Determine threshold and maximal stimulus. Ask when stop hearing it. Ulnar neuropathy at the elbow (UNE) is the second most frequent upper extremity compression neuropathy. I had the EMG and nerve conduction test done and because my problem is Thoracic Outlet Syndrome, not only did it barely hurt (really, the only place it hurt was when they put that long needle in the skin above my inner elbow) it was almost pleasantly tingly! I tested normal. Besides back pain or neck pain, some patients with a spine-related The presence of a nerve conduction abnormality after surgery does not, of itself, indicate persistent nerve entrapment because many patients with entirely successful surgery show considerable residual impairment of median nerve conduction when they are tested afterwards, even though they have no symptoms.


This test can determine if there is nerve damage and can how much. These tests can establish if a nerve is pinched, and give a numeric value to how severely it is pinched and often where it is pinched. What is a Nerve Conduction Test? A nerve conduction test is a procedure that is designed to identify nerve damage when such damage is suspected due to injury or a neurological condition. Studies have failed to provide clinical evidence that these tests improve health outcomes. Aside from the pinprick test to map out nerve deficit, PSSD testing can give objective evidence of an injury.


These nerve cells are known as motor neurons. The study does NOT examine the brain or spinal cord. I know I am not a doc nor do I have any medical training at all. When an EMG is done, it is to try and pinpoint the location of nerve damage. Anyway, I went on to have 3 steroid injections in the s1 nerve root, all of which did nothing.


The arrangements, and the way tests are performed, may vary between different hospitals. The first part is called Nerve Conduction Studies. Nerve conduction studies may not be of help immediately after the injury in many patients. NCV tests measure how long it takes nerves to transmit signals. Some doctors use hand-held "nerve conduction" devices to check for nerve damage caused by diabetes, pinched nerves, and other ailments.


A nerve conduction velocity (NCV) test is used to assess nerve damage and dysfunction. . Nerve Conduction Velocity Test This test provides some of the strongest evidence of carpal tunnel syndrome. My blood work is showing elevated levels of CK (inflammation of muscles). The bone conduction test will uncover if there is an issue in the center ear depression.


g. Why should we think hard when requesting nerve conduction studies (NCS) and electromyography (EMG)? Aside from the reasons that should determine our use of all investigations there are two particular issues that relate to these tests: NCS/EMG is at best uncomfortable, at worst painful, for the Electromyography and Nerve Conduction Tests are ordered to learn more about the health of peripheral nerves. Carpal Tunnel Syndrome (CTS) is the most common peripheral entrapment neuropathy. This two-part test is conducted most often in a hospital. electrodiagnostic reference values for upper and lower limb nerve conduction studies in adult populations shan chen, md, phd,1 michael andary, md, ms,2 ralph buschbacher, md,3 david del toro, md,4 benn smith, md,5 yuen so, md,6 kuno zimmermann, do, phd,7 and timothy r.


Symptoms of Lumbar Stenosis include low back pain, weakness, numbness, pain, and loss of sensation in the legs. As a result, HMSA will not cover these tests. Electromyography (EMG) / Nerve Conduction Velocity( NCV) This test is used to test the nerves and muscles in your entire lower extremity. nerve conduction studies to observe nerve behavior; 2 or more MRI scans to monitor changes in skin, muscles, blood vessels, and other tissues; When a primary care physician gathers evidence suggesting you may eventually be diagnosed with CRPS, he or she should refer you to a neurologist for ongoing diagnostic work and treatment. Usually, the response or signal is measured from the nerve itself or from a muscle supplied by the nerve being activated.


How to Code NCS Nerve Conduction Studies and EMG Electromygography. dillingham, md8 Unfortunately, one of the first steps in dx Polymyositis is the nerve conduction test and then a muscle biopsy. It is not practical or desirable to test every nerve in every patient, so we select a range of studies depending on the question being asked. This can be demonstrated with a ninhydrin test. So I'm just wondering how accurate are these tests an is there more types of nerve tests to check for this problem in case this was the wrong type to test for it.


it is like an test Read More. An electromyogram (EMG) is a test that measures the electrical activity of a muscle. Evaluation and Treatment of Failed Ulnar Nerve Release at the Elbow Failure after ulnar nerve decompression at the elbow can be defined as either no change in the patient’s symptoms or an initial improvement with recurrence, making the patient history essential in the work-up. Let me know how that conversation goes, will you? Measure the nerve signals’ strength and speed through a nerve conduction study. Campbell, MD, MSHAb INTRODUCTION The ulnar nerve may be compressed at several sites.


There are 2 parts to the test, nerve conduction testing, and an optional needle exam (see below). The test was of the right leg checking for sciatica. Failed EMG. Your nerve conduction test is not normal or negative if this is the diagnosis. Bone Conduction • 512/ 1024 Hz [256 if deaf] vibrating fork on mastoid behind ear.


There I had a nerve conduction test done on both hands and arms, but in say that I have had also had constant numbness in both foot feet at the base of my bigger toes for the last 3 years as well, more so in my left feet but when I have said to my GP about them they just say its due to my diabetes but as you say may be its all due to a spine problem, I will have to say to my GP next time I see him I had the EMG and nerve conduction test done and because my problem is Thoracic Outlet Syndrome, not only did it barely hurt (really, the only place it hurt was when they put that long needle in the skin above my inner elbow) it was almost pleasantly tingly! I tested normal. Blood tests may show what is the cause, but in my case they didn't come up with any reason for the symptoms. I was correctly CFS-diagnosed in 1996, in NY. This then leads to the fact that if you could generate a test signal up or down the nerve, you could measure the speed of the nerve’s conduction. Nerve conduction velocity (NCV) and electromyography (EMG) tests are sometimes used to help diagnose diabetic neuropathy.


An EMG is one tool for evaluating muscle weakness. • When stop hearing it, move to the patients ear so can hear it. Almost all leave feeling they worried for nothing. Neurologists use EMG to test nerve conduction speeds in order to assess neuropathic and myopathic disease states. Nerve Conduction Velocity and Electromyography Tests .


Nerve conduction velocity (NCV) — This test will measure the speed of electrical impulse as it moves through the nerve. • Normal: air conduction [ear] better than bone conduction [mastoid]. This is a good test for distinguishing these two conditions. I'm having a nerve conduction velocity test on my R arm this Thursday. Note: the information below is a general guide only.


The speech test researches whether there could be issues with the sound-related nerve which sends signals from the ear to the mind. An example of a therapeutic nerve block used to treat chronic pain is the Stellate Ganglion Block, performed in the front of the neck to treat Complex Regional Pain Syndrome (CRPS or RSD). Take an image of the brain and spinal cord by using magnetic resonance imaging (MRI). I had to appeal this as an re-consideration since they failed to rate a claim that was applied for in Feb 2010. And also full professors.


Nerve Conduction Velocities (NCV) A nerve conduction velocity test, or NCV, measures the rate of nerve conduction (how fast an electrical impulse moves through your nerve). He then had both an (NCV) and EMG Test done which just confirmed that he has a problem. Is it possible that my EMG/nerve conduction study results were not correct? I'm wondering if it really could be piriformis syndrome but presented as s1 dysfunction on the testing because the s1 is the nerve supply for the piriformis. Now this individual told a friend of his that he duped the doctor and us to get the disability insurance. I'm guessing, Carpal Tunnel surgery will be on the table, since rest and corticosteroids have 'failed' to fix the problem.


Vicki-s. Every effort is made by Dr. I have been told that there doctors who conduct this test and know exactly how to "rig" it to show no damage, or negative. C. The electrodes transmit this information to a machine that magnifies the electrical activity and provides a graphic representation of brain waves.


I told him about the nerve test that had ben done an the results from it an he said that it was wrong. Negative EMG/NCV so I don’t have neuropathy? Not so fast!! (You can skip to the chase here – you CAN have peripheral neuropathy with a normal EMG/NCV). This is done to check the speed of the nerve. Neuro said Nerve Conduction Study showed my nerves were worse than the first one I had done a year and a half ago, even after IVIG and the fact that I feel so much better. It detects any signs of blocking or slowing down of responses to nerve stimulation.


For a motor nerve we can test from the cell body to the muscle. They help identify, for example, whether a patient's problem is in the spinal cord, muscles, nerves leading to muscles or other structures in the body. in Pernicious Anaemia Society 2 years ago. 3. Electromyelogram (EMG) and Nerve Conduction Velocity Testing (NCV) An Electromyogram is an electrical testing of the muscles and indirectly of the nerves in your body via a nerve conduction study.


If my right arm nerves fail, then there's a problem in it (pintched nerve). Learn about what a normal result looks like and what an abnormal nerve conditions study looks like. I had a nerve conduction test done in 1994, my first CFS year, when 6 MDs were stabbing in the dark trying to diagnose me. Nerve conduction studies (NCS) are usually done in conjunction with electromyography. Our surgeons realize that many times patients can find relief from their symptoms through a variety of conservative treatments How to fail a nerve conduction test.


The results of this test are often correlated with the results from the Nerve Conduction Study, which is customarily done first. The techniques and how they are affected by disease are described in general terms. During the test, the nerve is stimulated, usually with surface electrode patches attached to the skin. Electromyography (EMG) is a test that measures the electrical activity of your muscles. The response from your nerve is recorded by an EMG machine.


When I told him he was doing the wrong leg he read my chart then removed what he had connected. Management however should be guided by the underlying pathology rather than the symptom, and hence the importance of having a test on the nerve and muscle functions. NCS can also provide information regarding the condition of the nerve fiber. getting a Poke'mon stuck. The test consists of two parts, though at times one may be done without the other.


Basic Nerve Conduction Studies Holli A. Masceri and his staff to make you feel as relaxed and comfortable as possible. This test evaluates peripheral nerves. fail fail fail fail fail fail fail fail fail fail Just a quick question if anyone has a bit more knowledge about this, I'm getting a nerve conduction study on wednesday (I'm not diagnosed, had normal brain mri and normal bloods but several neurological symptoms), if a problem is detected by nerve conduc study, would that pretty much rule out ms as the problem would be peripheral? Although the remaining 6 MS and NMO patients showed NCS abnormality, indicating the existence of peripheral neuropathy, that is, nerve conduction velocity slowing, conduction block, prolonged duration, low amplitude, and reduced F-wave occurrence, they did not fulfill the EFNS/PNS electrodiagnostic criteria for definite or probable CIDP. It measures how fast an electric signal can travel along a nerve or from the nerve to a Also called an electroneurography, EneG, or nerve conduction study, a nerve conduction velocity (NCV) test is a measurement of the speed of conduction of an electrical impulse through a nerve.


These principles can be applied to specific conditions discussed elsewhere. Measure the conduction velocity of the frog sciatic nerve. I posted these results for others who may not understand what the stuff means. Also known as a nerve conduction study, the procedure measures how quickly electrical signals move through My nerve conduction test showed everything was okay. Normal & Abnormal Nerve Conduction Study (NCS) Findings Below are a few examples of common EMG/NCV abnormalities in several peripheral nerve disorders.


Open the Johns Hopkins Medicine menu with the enter key and close it with the escape key; use the tab keys to navigate links. 5 ms)b. Carlin on failed peripheral vision test: If your nerve conduction test showed you have carpal tunnel syndrome, that is your diagnosis. The test is based on placing needles into the arm or leg and measuring the length of time required for an electrical signal to pass down the nerve root. Prasad: “EMG stands for Electromyogram and NCS stands for Nerve Conduction Study.


2. Here an electrical impulse is sent down the length of the nerve. the American Association of neuromuscular and electrodiagnostic medicine developed this video so you know what to expect during a nerve conduction study and electromyography or EMG test you've been sent to the EMG clinic to evaluate your nerves and muscles the tests will help the doctor who referred you determine if your muscles or nerves […] Dr. He told me with ALS you have axonal damage (fail the EMG) but would pass the nerve conduction test. Clinical Features and Electrodiagnosis of Ulnar Neuropathies Mark E.


I had my second Nerve Conduction Study and EMG on Friday. Also to make matters worse I wasn't able to have the nerve test done do to blood pressure was to high, and was documented as such for the compensation claim. In this test, the nerve is electrically stimulated, and the electrical impulse 'down stream' from the stimulus is measured. o. It will not show if the nerve is been compromised by muscle or disc compression.


The test provides information about the muscle itself and shows how well it receives stimulation from the nerve. Electromyography (EMG) and nerve conduction velocity (NCV) are electrodiagnostic tests that measure the electrical activity of muscles and nerves. Learn more. Nerve conduction tests are not always accurate, and should not be the determining factor alone of the extent of your injuries. Nerve conduction studies are most commonly performed for conditions that cause symptoms in the arms or legs.


The EMG and nerve conduction study is a mildly uncomfortable test. It measures how fast an electric signal can travel along a nerve or from the nerve to a Please, Please, dont' have EMG/nerve test if you're already diagnosed with RSD!!!!! If you ever pay any attention at all to anything I say please listen to this. I recently had a nerve test done and the results came back abnormal. The other is a nerve conduction study (NCS Physicians will generally carry out a nerve conduction study (NCS) — also called a nerve conduction velocity (NCV) test — prior to ordering an electromyography (EMG) to diagnose amyotrophic lateral sclerosis (ALS). In a variation of electromyography, two electrodes are taped to your skin.


Electrical signals are passed along nerve cells throughout the body to relay messages, for example, to tell a muscle to contract. Chronic cervical nerve root compression refers to nerve irritation caused by damage to the disc between the cervical vertebrae, so that the disc presses on the nerve root as it leaves the bony spinal column. , NC-stat System, Brevio ® nerve conduction monitoring system) The nerve conduction test won't show you what is wrong. EMG Test Came Back Negative and I have Neuropathic pain, WHY??? I pulled my back muscle in the lower lumbar area a year ago, two weeks after I started experiencing neuropathic pain in my left leg (the worst) and mildly in my right arm. Electrodiagnostic tests evaluate diseases of the nerves and muscles.

Most nerve conduction studies involve stimulating specific nerves or nerve areas, usually through electric pulse, in order to measure response. Nerve conduction study is an electrical test which involves the stimulation of nerves along several points (usually as they run down the arms or legs).


These tests are valuable diagnostic tools that help neurologists locate and determine the causes of diseases that affect your muscles and nerves, as well as assess how much damage there is. If I understand this correctly, please correct me if I'm wrong. Horak, MD University of Arizona August 2015 . The test can last anywhere from a half an hour to an Nerve Conduction Velocity (NCV) Testing What is a NCV test? A nerve in the body works somewhat like an electrical wire in your house. Your nerves send signals to your muscles to help them move.


I failed both which i guess is good The Nerve Conduction Study tests how signals travel along the nerve, helping to isolate the cause of abnormal nerve function. How do you fail nerve conduction survey? When do you not conduct marketing survey? When swimming with dolphins. That was in Columbia, MO and all the docs were "brilliant" MDs at the Univ of MO medical school and hospital. A small shock is passed through the median nerve to see if electrical impulses are slowed in the carpal tunnel. EMG/NCS – FREQUENTLY ASKED QUESTIONS (FAQ) What does the EMG/NCS test?

This test is used to detect signs of nerve injury. A nerve conduction study (NCS) is usually done at the same time as an EMG. if my right arm nerves pass, then the problem futher up the line (spinal cord, brain).


The nerve will be stimulated by an electrode patch attached at one end and the electric impulse is recorded by another patch. Most patients find this test to be somewhat uncomfortable. Speech audiometry -- This tests your ability to detect and repeat spoken words at different volumes heard through a head set. Nerve conduction studies are less accurate in the early stages of carpal tunnel syndrome and in younger patients (Wilder-Smith E et al, 2006). Other simple nerve tests include Tinel's and Phalen's testing (see pictures below).


Nerve Conduction Studies (NCS), are generally performed along with EMG test to further evaluate nerve disease. A nerve conduction test involves activating nerves electrically with small safe pulses over several points on the skin and measuring the responses obtained. ) Description: (cont. In general, any motor, sensory or mixed nerve study slower than 35 m/s in the arms or 30 m/s in the legs signifies demyelination. This test measures the electrical activity of the muscles.
